J'essaie de passer par l'exemple SSL et l'exemple EchoServer dans Netty et pour une raison quelconque, quand j'ajoute mon sslContext du côté client, je reçois, an established connection was aborted by the software in your host machine
.ne peut pas se connecter avec ssl dans netty

Y a-t-il quelque chose d'évident qui me manque? J'ai essayé de suivre cet exemple et de le modifier un peu (http://netty.io/4.1/xref/io/netty/example/securechat/package-summary.html), mais je continue d'obtenir cette exception lorsque j'ajoute le sslContext au canal client. Des pensées? Merci.
Quelle version de netty utilisez-vous? En utilisant netty 5.0 votre exemple fonctionne bien – Ferrybig
@Ferrybig version 4.1.9 – Crystal
